Chris Dastou was playing with his children in a swimming pool on the Disney Fantasy cruise ship when he felt something brush against his feet.

Assuming it was his 6-year-old son, Dastou hooked a foot around the little body and lifted it out of the 5-foot-3-inch-deep water.

To his shock and horror, Dastou found himself cradling a limp, 4-year-old stranger.

He carried Chase Lykken to the side of the Donald family pool and laid the boy on his back. The child's skin was blue, waxy and pale. He wasn't breathing.

"I started screaming for help, and everybody rushed over and grabbed him and started to help out," recalled Dastou, 35, manager of a car dealership near Atlanta.

Immediately, dozens of passengers clustered around Chase, a Minnesota boy who suffered severe brain damage when he nearly drowned March 30 on the ship docked at Port Canaveral, a police report obtained by the Orlando Sentinel on Tuesday shows.

Chase Christopher Lykken was deprived of oxygen for up to six minutes, Port Canaveral police determined.

He was on life support at Arnold Palmer Hospital for Children in Orlando before being transferred last month to Gillette Children's Specialty Healthcare, a St. Paul hospital for kids with disabilities. His prognosis is "most likely poor," a doctor for a child-protection team in Orlando concluded.

"Chase is described as being in a vegetative state," the doctor wrote April 9 in a report submitted to the Florida Department of Children and Families.

Investigators concluded Chase was inadequately supervised, but there was no criminal intent, police said. They called the incident a "tragic accident."

Police could not determine how Chase slipped away and landed in the pool. An 8-year-old South Carolina girl told investigators she saw Chase and another boy wrestle near the pool and fall in, but neither video nor other witnesses corroborated her account.

Ship video shows the Lykken (pronounced LICK-un) family on the Mickey pool deck at 3:04 p.m. Seven minutes later, parents Christopher and Lisa Lykken appear to be looking for someone, the report states.

At 3:12 p.m., Chase was pulled from the Donald pool, where signs warn passengers that no lifeguard is on duty. The pools are next to each other, a Disney spokeswoman said.

The parents told officers they lost sight of Chase but assumed he was at the pool with his 9-year-old brother, Tanner, and 7-year-old sister, Ava. Lisa Lykken, 43, looked for Chase in the Mickey and Donald pools, then heard Tanner yell and saw someone performing cardiopulmonary resuscitation on Chase, according to the report.

Chase's parents, who live in Prior Lake, about 25 miles south of Minneapolis, have not granted media interviews. They keep friends, family and well-wishers apprised in painstaking detail on a Facebook page dedicated to Chase and on caringbridge.org.

There, readers can see Chase in happier times: on the first day of preschool; catching a fish; posing with his siblings and mugging for the camera, his arms aloft and fists clenched.

Despite the odds, the family hopes for a miracle and expresses gratitude for the smallest signs of progress. Many of the posts end with, "God is good."

The Lykkens have the support of nearly 6,700 people who had liked the Facebook page by Tuesday. Many said they pray for his recovery. Some have adopted the red, white and blue Captain America shield logo as their profile picture to show solidarity with the blond, brown-eyed boy who loved to dress as the comic-book superhero.

A red, $5 "CHASE'S WARRIORS" bracelet to raise money for his care was so popular that the initial shipment sold out.

The medical news is grim, however. Chase is breathing on his own but is being fed through a tube, according to posts. The areas of his brain that control motor skills, basic functions such as heart and respiratory rates, temperature, the sleep-wake cycle and eyesight were damaged.

"It's just a very sad situation," said Dastou, the man who pulled Chase from the water. "It was unbelievable what happened. Nobody would think anything like that would happen."
